Yes.  "errorlines" relates to "errorbars" the same way "linespoints" 
does to "points".

The output of... what?  Here's an example:

	plot '-' u 0:0:(1.0) w errorlines, \
              '-' u 0:($0+2):(1.0) w errorbars
	  0
           1
           2
           3
         E
	  0
           1
           2
           3
         E

No.  If that were what it did, it would be called "errorband" or 
"corridor" ;-)
